I Be .it known that 1, JOHN F, LEss1NG, -a citizen of the United States, and resident of St. Joseph, Berrien County, lMichigan, have invented a certain new and useful Improvement in Automatic Weather Strips, of which thefollowing isa specification.

This invention relates to weatherstrips for the lower edges of outside doors, such as storm doors, or doors for the 'front and rear of houses,"or other buildings, to keep the. cold-air fromcomi'ng in under the lower edge of the door. I r I Generally stated, the object of the invention is to provide a novel and improved construction, whereby a weatherestrip of 'thiskindwill be operative and effective struction and combinations tending to in to produce the desired result, when the door is closed, by tightly sealing the slight space ordinarily found between the lower edge of the door and the, threshold, but which will ordinarily rise when the'door is swunginwardly, thereby to passreadily over a carpet or rug, or anything else on the floor immediately inside of the door, and which will then automatically move downwardly when the door is closed, thereby ,to again make firm contact with the threshold of the door,

the door.

It is also an object of the invention to provide certain details and features of concrease the general efiiciency and desirability of an automatic door threshold weatherstrip of this particular character.

. To the foregoing and other useful ends,

lower edge of the door, embodying the prin- Figure .2 is a horizontal section, on' a larger scale, on line 22 in Figure 1; and.

Figure. 3 is a vertical section,-on.-a still larger scale, on line 3 3 1n Fl'gure'l.

As thus llustrated, the invention comprises ahinge ].,,.secured to the door frame 2. immediately below theadoor hinge 3, in the manner shown, and provided with a long strap 4; having slots 5 through which screws 6 are inserted into the door 7 This slides back and forth on the screws '6, end- :wise, :when' the door is opened and closed;

' latter 'may be. of .anylsuitable character. i The hinge lii's so located that the,strap 4f The eatherstrip Smay be composed ofany suitable material, such as metal, provided at its lower edge 'with'soft material, such as rubber, to engage the threshold' 9 of the doorway. The Weatherstrip 8, is preferably provided with a slot: 10," through which a screw-J1 is inserted: intoth'e door, so that the-Weatherstrip is movable up and down, "and for-this purpose guides 12"for the ends of the Weatherstrip are applied to the side 15 are disposed'at'such an angle; it will be to more up and' down seen, that the relative endwise movement of the strap 4:, when the door is opened, will cause the pins or screws 14 to rise in the slots 15, thus lifting .the Weatherstrip 8 a distance above thee-floor, so that it will pass over a rug or carpet, or anything else land on the floor immediately inside the'door. Then, when the door is closed, the endwise edge portions of the door, whereby the 1 movement of the strap 4, and the consequent cam action of the edges of the slots 15in co-operation wlth. the pins or screws. 14-,

'will ca'usethe weatherstrip 8 to move down into engagement with the threshhold'il, pre- T 1viously mentioned. w

Thus, an automatic weatherstrip is *provided for the :lower edge ofthe door,.adaptred to automatically engage the threshold when the door is closed, to prevent cold air from entering under the door. This autoina tic Weatherstrip, when the-door is opened,

automatically rises to provide full clearance for the lower edge of the door that passes over alcarpet or rug laid onithe floorimmediately inside offthe door.

It will beunderstood, ofjcourse, that the I invention is not limited to the exact construction shown and de.scribed, as an; automatic Weatherstrip for' the lower edge of a door, or for a window, or other outside closure, ofthis general, character, may have any suitable construction, so that it will automatically move up and downwhen the 1 door is opened and closed, without departing from the spirit of theinvention,

1 an undesirable offthe door.

XV-ith ut disclaiming; anything and With-v .out' prejudice to: any novelty disclosed, What- I='claimvas-niy iiwentionais: I j 1- 'lh'e combination with a door orjot-her lVhile the invention .is shown in the form outside closure, of; an: autoinaticiweath'erstrip for-the lower edge thereof, comprising instrumental'ities for causing the- Weatherstrip to iaiiitomatically move up and: down when tlie doori; isopened; andf cl'osedi, said-instrunient alit-ie'st comprising a hinge; connection l etween the; door an dr the; doorway, co1niprisinga member having; movement] horizon? tally and. endwise relatively "toyt'l'ie'tloor.

when thedoor-is-open'ed or closedgsaid memher having a camming action With the a Weatherstrip, whereby. said endwise movement causes the Weatherstripto rise when the-doom is; op enedrand causes the Weather strip to move downward when the door closed:

2. A structure as specified in claim 1, said hinge connection being out of line with the hinges ofthe door, sotliatisaid door swings about: oneaxis; while said member swings about another axis. I
